MATTRESS-FILLIN G MACHINE.

Specification of Letters Patent.

Patented July 28, 190s.

Application filed December 4, Serial N o. 405,005.

To all whom it may concern:

Be it known that I, EMIL ZoFNAss, a citizen of the United States, andresident of Boston, in the county of Suffolk and State of Massachusetts,have invented new and useful Improvements in Mattress-Filling Machines,of which the following is a specification.

My invention relates to mattress filling machines and its object is toprovide certain improvements in mattress filling machines of thecharacter set forth in Letters Patent of the United States N o. 656,833dated August 28, 1900.

Said improvements will be hereinafter described and pointed out in theclaims.

In the accompanying drawings, in which like parts are indicated by likereference numerals,-Figure 1 is a side elevation of the front end of amattress filling machine containing certain embodiments of my invention3 Fig. 2 is a plan and sectional view on broken line 2 2 of Fig. 1; Fig.3 is a sideI elevation of the rear end Aof said machine; Fig. 4 is aplan view of the rear-end of said machine; Fig. 5 is a side elevation ofthe ticking holder presently to be described; Fig. 6 is a detail Viewshowing an elevation of the end of part of said ticking holder; and Fig.7 is a detail view of one of the cross members of said ticking holder.

The frame of the machine consistsof uprights 1, 1, suitable horizontalbars as 2, 2, and the longitudinal outer boards 3, 3. The boards 3, 3are tapered at their front ends, as shown in Fig. 1 to admit of thearrangement of the feeding and compressing aprons presently to bedescribed. At the front end of the machine a shaft 4 is 'ournaled insuitable bearings 5 secured to t e front u rights of the frame; and atthe rear end of t e machine a shaft 6 is journaled in suitable bearings7 secured to the rear uprights of the frame, at the same level withshaft 4. Said shafts are provided with sprocket wheels 8, 8, carryingthe endless chains 9, 9 ,-one at either side of the machine, extendingbetween the front and rear shafts 4 and 6.

as shown, and adjacent tothe inner side of said apron for such distancealong its oper ative stretch as is desired. As many rows of theserollers may be employed as desired, but under ordinary conditions tworows will be found satisfactory. The row or rowsof rollers may extendtoward the rear of the machine as far as desired, but I have found itsufiicient to extend them back to a point where the compression of thefilling material, when the machine is operating, first tends to causesufficient friction between 'the apron and its support to createsubstantial heating between the moving parts. Without the use offriction rollers, especially near the delivery end of the machine wherethe compression is greatest, the parts tend so to heat that there isdanger of fire. The lower apron is driven through pulley 13, receivingpower from some external source, shaft 14 on which said pulley ismounted, s ur gear 15 onv shaft 14, spur gear 16 in mes with gear 15 andsecured on shaft 4.

The u per apron 17, which is constructed like the ower apron heretoforedescribed, is mounted on sprocket wheels 18 and 19 secured respectlvelytov shafts 20 and 21. Shaft 21 is supported by and j ournaled on abracket 22 attached to one of the uprights of the frame of the machine.A frame work for the upper apron is provided by which the upper apronmay be adjusted relatively to the lower apron, comprising bars 23 havingbearings-24 at the rear end by which the bars are supported on shaft 21,and having bearings25 at the front end in which shaft 20 is supportedand j ournaled. The upper and lower aprons converge toward the front endof the machine as shown, the upper apron inclining downwardly from rearto front. In order to vary the space between the delivery ends of saidaprons, and thus vary the thickness or density of the mass of fillingmaterial as delivered,` and so adapt the machine for making mattressesof different thicknesses, the front end of the upper apron is verticallyadjustable, the frame work carrying the upper apron swinging on shaft 21as a pivot. This vertical adjustment is eected by screw shaft 26,mounted in a threaded lug 27 secured to the upri ht 1, and engaging atits lower end with aracket 28 fastened to the bar 23. A preciselysimilar device is pro- 'vided at the opposite side of the machine,

and both may be operated simultaneously b a chain and sproc etconnection 29. Antii friction rollers' 30 arranged tandem are supportedadjacent to the lnner side of the uper a ron 17 in a manner similartothe above .lengthwise throughout the'wh'ole length of the machine. Theseside boards are ta'- pered at 'their forward ends to fit between theconverging aprons and are substantially similar in orm to the outerboards 3, 3 above described., f Side boards 31 31, are both laterallyadjustable, simultaneously and equally toward or from each other, thusinsuring that the work of com ressing and feeding the fillingmaterial'sha always be central of the machine, that is, symmetrical withrelation to the central axis. The antifriction rollers therefore remaincentral or symmetrical with relation to the central axis of the work inwhatever positionthe side boards 31, 31,

may be adjusted. At the delivery ends of the side boards 31, 31, are thebrackets or arms 32, 32, extending forward'in front of the machine. Themeans by which the side boards are adjusted simultaneously and equallytoward and from each other comprise cross shaft 33 journaled in suitablebrackets 34 secured to some art of the machine as the boards 3, 3, saidshaft 33 being-provided at one end with a ri ht handed screw threadedsurface, and at lts other end with a left handed screw threaded surface,said screw threaded surfaces engagin respectively with correspondinglythreade bores provided within hubs 35 on brackets 32. .At'one end ofshaft 33 is aJ bevel gear 36, in mesh with bevel ear 37, secured at theend of shaft 38 journa ed on the framework of the machine,

. and extending from front to rear of the mai chine. At the rear end ofthe machine cross shaft 39 is provided journaled in suitable brackets 40on boards 3 and having right and left-handed screw threaded surfacescoperating with screw threaded bores provided therefor inthe side boards31 in a substantially similar manner to that above described withreference to the front shaft 33. Gear connection between shaft 38 andshaft 39 is provided consisting of bevel gears 41A and 42, and theintermediate shaft 43 journaled on bracket 40.

At some convenient point on shaft 38 its longitu inal axis, such as thespiral gear 44 mounted onbracket 45 secured to board 3, and spiral gear46 secured to shaft 38, A crank handle`47 is provided for turning glear44 which im arts a rotary movement to s aft 38 through tihe gear orscrew46. When shaft means are (provided for rotating the same on 38 isrotated it imparts a rotary movement to both front and rear shafts 33and 39 which in turn cause the side boards 31, 31, simulta-.. v

.and adjacent to the deliveryv end of the machine, expa'nsible andcontractible in direce tion of the width of the machine. Eachof "theexpansible and contractible side members comprises plate 48 and plate49. Plate 49 has an upwardly extending projection 50 rovided with a slot51. Plate 48 is bent ackwardly upon itself as shown at 52 so that theparts 48 and 52 embrace said projection 50. A headed stud 53 is mountedin part 52 registering with slot 51 through which the shank of the studextends and under which the head of the stud is held. An internallythreaded hub 54 engages with the correspondingly threaded end of theshank of stud 53 and is provided with a handle 55, by turning which theplate 48 may be clamped upon or loosened from the projection 50 at anydesired point of adjustment Within the vertical slot 51. Thus the plates48 and 49 may be vertically adjusted with relation to each other toexpand or contract the ticking holder in depth. The projection 50 alsoextends be'- low plate 49 as well as'above plate 49 and is piv'otallysecured at 56 to the sup orting arm 32. A curved slot 57 described)labout pivot 56 as a center, and a headed screw stud 58 mounted inthe'part 50, admits of swinging the ticking holder upward and forwardand of clamping it at any 'desired position of angular adjustment, thusaffording convenient and rigid means for placing the ticking upon thetickin holder and thereafter swing-- ing the ticking older intooperative position and there fastening it. c

It will be understood that the mattress ticking is placed on theticking-holder in Van inside-out condition, the ticking being Acrimpedor puckered in order to get it all on the tlckingolder that the closedend of the ticking is presented in an in side-out condition to thedelivery end yof the machine, the ticking-holder belng in the positionshown at Fig. 1; and that, as the mattress filling material is fed outof the machine, it causes the ticking to be reversed, the filled part ofthe mattress be'mg forced between theside plates and the cross rods ofthe ticking-holder. It is to facilitate the rapid'and easy placing` ofthe ticking on the tlcking-holder that the latter is pivoted to the.arms 32 to permit it to be swung upward and forward.

bers. are provided connecting respectively the Expansible andcontractible cross meml ticking holder, the same ticking ho uppercorners and the lower corners of the side plates of the tickinggholderadjacent to the delivery end of the machine. These cross members consistof inwardly projectingopposed rods and 61 secured to the op osite uppercorners of said side members an connected by a telescoping sleeve 62.Sleeve 62 is of sufficient length to remain in engagement with and toconnect rods 60 and 61 in all adjustments of the ticking holder from itsposition of contraction to its position of extreme expansion. i

It will thus be seen, that, Asince the ticking holder is supported byarms 32, 32, carried by the adjustable side boards 31, the tickingholder will be expanded or contracted automatically and simultaneouslyin Width with the lateral adjustment of the side boards 31, 31, theticking holder thus at all times being of a width corres onding with thewidth of the compressed fling material and of the mattress to bestuffed. Noindependent adjustment of the ticking holder by the operatoris required when assing from the manufacture of one size of) mattress toanother size. It will also be seen that by reason of the adjustabilityin de th of the Fder can -be used by making a similar adjustmentwhenever the upper apron is adjusted vertically to stuff mattresses ofvarying thickness; whereas heretofore when varying -thevdimensions ofthe mattress it has been necessary to remove the ticking holder andsubstitute anotherone therefor of different size.

In order to drive the upper apron 17 which is vertically adjustable atits frontend, by mechanism which shall remain operative and shall notrequire adjustment when the apron is adjusted, I provlde a chain andsprocket drive connecting the rear apron shaft 21 whose location isfixed, with the driving shaft 14. This driving connection is shown indotted lines in Fig. 1, sprocket wheel 66 being secured to shaft`14, srocket wheel 68 secured to shaft 21, and c sprocket wheels The method ofapplying the ticking to the ticking holder and the general operation ofthe machine, excepting as hereinbefore specified, is substantially thesame as described in said Patent No. 656,833 and no detailed descriptionthereof is here necessary.
